Recently one of our Application Engineers was asked if a vibratory style level sensor could be used to detect heavier bulk solids materials such as metal shot blast media.
Our Application Engineer responded by mentioning that a vibratory type level detector can indeed be used to detect shot media. However, due to the nature of the vibratory technology, this type of sensor would require a protective baffle to be installed if it is employed where heavier materials are stored or in a dynamic process where the material may be shifting en mass (see baffle examples above). Most designs for the vibratory type level detectors contain a sensing element, that if bent as a result of mishandling or exposure to excessive process dynamics the sensor can be rendered ineffective. Of course, the heavier the target media the greater the chance of the sensing probe suffering damage.
Heavier powder & bulk solids materials like metal shot blasting media may be even better served by a bin level indicator which is more rugged. Monitor's model MK-2 R.F. Capacitance level detector is recommended. This instrument is designed with a sensing probe constructed of a solid T316 SS and even if deflected will continue operating. It is very rugged.
